BACKGROUND

Field

Embodiments described generally relate to protection barriers, such as floor protection barriers, and methods for making and using same.

Description of the Related Art

During construction, renovation, and/or other activities within a building or other structure one or more finished surfaces therein frequently need to be protected to reduce or prevent scratching, marring, or other damage. Attempts to protect finished surfaces have included placing sheets or layers of plastic, cloth, or paper on the finished surface to serve as a temporary barrier. While providing some protection to the covered finished surface, these layers of plastic, cloth, or paper do not always provide the desired level of protection to the finished surface intended to be protected.

There is a need, therefore, for improved protection barriers that can be disposed on floors, decks, counter-tops, or other surfaces of a building or other structure.

SUMMARY

Protection barriers, such as floor protection barriers, and methods for making and using same are provided. The protection barrier that can include a base sheet and an energy absorbing layer. The base sheet can have two or more paperboard layers and one or more sizing layers. A first paperboard layer can form a first surface of the base sheet, a second paperboard layer can form a second surface of the base sheet, and the one or more sizing layers can be disposed between the first and second paperboard layers. The energy absorbing layer can be secured to the second paperboard layer. The protection barrier can have a water vapor transmission rate of about 5 g/645.2 cm²/24 hr to about 150 g/645.2 cm²/24 hr, as measured according to ASTM E96M-14, Procedure A. The sizing layer can include an average oil and grease resistance value of about 6 or greater, as measured according to TAPPI T-559 standard test for Grease Resistance for Paper and Paperboard. The protection barrier can include an oil and grease resistance flotation value of about 3 hours or greater, as measured according to the Georgia-Pacific Flotation Paper Saturation Test STP-415.

The protection barrier can be made by forming the base sheet that can include the first and second paperboard layers and one or more sizing layers and securing the energy absorbing layer to the second paperboard layer on the base sheet.

The sizing layers 119 and/or 219 can have an oil and grease resistance (OGR) property for providing a barrier to one or more oils, greases, fats, or other organic-based compounds or materials. Illustrative organic-based compounds or materials can include, but are not limited to, oils, greases, fats, organic solvents, motor oil, hydraulic fluid, brake fluid, automatic transmission fluid, or any mixture thereof. In some examples, one or more of the layers 117, 217, and/or 230 and/or the energy absorbing layers 125 and/or 225 can have the OGR properties as the sizing layers 119 and/or 219.

In one aspect, the OGR property can be measured or otherwise determined by using a test kit referred to as the “3M Test Kit” (TAPPI T-559 standard test for Grease Resistance for Paper and Paperboard, established by the Technical Association of the Pulp and Paper Industry, Norcross, Ga., USA; and commercially available from 3M Company, St. Paul, Minn., USA). The “3M Test Kit” includes 12 solutions composed of castor oil, toluene, and n-heptane having various concentrations. Each oil solution can be applied to a sample portion of the sizing layers 119 and/or 219. The highest numbered solution (the most aggressive) that remains on the surface of the sizing layers 119 and/or 219 without causing failure (e.g., soaking through the layer) is scored as integers from 0 to 12 (worst to best) based on the liquid wetting and penetrating and is reported as the OGR value. The test can be repeated multiple times and the average OGR value can be calculated for each sample.

The sizing layers 119 and/or 219 can independently have an average OGR value of about 6, about 6.2, about 6.4, about 6.6, about 6.8, about 7, about 7.2, about 7.4, about 7.6, about 7.8, about 8, about 8.2, about 8.4, about 8.6, about 8.8, about 9, about 9.2, about 9.4, about 9.6, about 9.8, about 10, about 10.1, about 10.2, about 10.3, about 10.4, about 10.5, about 10.6, about 10.7, about 10.8, about 10.9, about 11, about 11.1, about 11.2, about 11.3, about 11.4, about 11.5, about 11.6, about 11.7, about 11.8, about 11.9, about 12, as measured according to TAPPI T-559 standard test for Grease Resistance for Paper and Paperboard. In some examples, the sizing layers 119 and/or 219 can independently have an OGR value or an average OGR value of about 6 to about 12, about 8 to about 12, about 10 to about 12, about 8 to about 11, or about 6 to about 10, as measured according to TAPPI T-559 standard test for Grease Resistance for Paper and Paperboard.

The OGR property of the protection barriers 100 and 200 can be measured or otherwise determined by using a boat float test, according to the Georgia-Pacific Flotation Paper Saturation Test STP-415. In the boat float test, the protection barriers 100 and 200 are folded into a boat-shaped sample, then floated in a wetting solution for a given time period. An OGR flotation value can be determine by the amount of time that the boat-shaped samples have successfully remained floating in the wetting solution (as opposed to sinking in the wetting solution). The wetting solution can be or include one or more organic based compounds, oils, greases, organic solvents, motor oil, hydraulic fluid, brake fluid, automatic transmission fluid, standardized hydrocarbon solutions, such as any of the solutions from the 3M Test Kit (e.g., solutions can include castor oil, toluene, or n-heptane), or any mixture thereof. As used herein, unless otherwise noted, the OGR flotation values can be measured according to the Georgia-Pacific Flotation Paper Saturation Test STP-415 with automotive brake fluid at a temperature of about 100° C.

The protection barriers 100 and/or 200 can be folded into a boat-shaped sample, such as by folding about 2.54 cm of each side of a square sample having side lengths of about 15.24 cm for each protection barrier 100, 200. Each protection barrier 100, 200 can be folded so that the upper surfaces 102, 202 are facing inward and upward so to be within the boat-shaped sample while the lower surfaces 104, 204 are facing downward and outward so to be outside of the boat-shaped sample. Each of the corners of the boat-shaped sample can be stapled. The wetting solution (e.g., hydraulic fluid or automotive brake fluid) contained within a vat can be heated and maintained at a temperature of about 100° C. The boat-shaped samples of the protection barriers 100, 200 can be placed into heated wetting solution such that the upper surfaces 102, 202 are disposed facing away from the wetting solution and the lower surfaces 104, 204 are disposed facing into the heated wetting solution. The time that the boat-shaped samples of the protection barriers 100, 200 can be monitored and recorded for any time period, such as, for example, about 30 seconds or about 3 months.

In some examples, the protection barriers 100 and/or 200 can have an OGR flotation value of about 0.1 hr, about 0.5 hr, about 1 hr, about 2 hr, about 3 hr, about 4 hr, about 5 hr, about 6 hr, about 7 hr, about 8 hr, about 9 hr, about 10 hr, about 11 hr, about 12 hr, about 13 hr, about 14 hr, about 15 hr, about 16 hr, about 17 hr, about 18 hr, about 19 hr, about 20 hr, about 21 hr, about 22 hr, about 23 hr, about 24 hr, about 25 hr, about 26 hr, about 27 hr, about 28 hr, about 29 hr, about 30 hr, about 50 hr, about 100 hr, or longer, as measured according to the Georgia-Pacific Flotation Paper Saturation Test STP-415. In some specific examples, the protection barriers 100 and/or 200 can have an OGR flotation value of about 4 hr to about 24 hr. In other specific examples, the protection barriers 100 and/or 200 can have an OGR flotation value of about 8 hr to about 24 hr. In other specific examples, the protection barriers 100 and/or 200 can have an OGR flotation value of greater than 24 hr or greater than 48 hr.

The OGR property of the protection barriers 100 and 200 can also be measured or otherwise determined by using a spill catch test. In the spill catch test, a sample of the protection barrier 100 or 200 is disposed onto a flooring surface, then a wetting fluid is added to the upper surface 102 or 202. After a given time period, the flooring surface is checked for the presence of the wetting fluid. An OGR spill-catch value can be determine by the maximum amount of time that lapsed from exposing the wetting fluid to the sample to the time the flooring surface is checked and remains free of the wetting fluid. The protection barrier sample can be a square sample having side lengths of about 15.24 cm for each protection barrier 100, 200. The wetting fluid can be in an amount of about 10 mL and can be or include one or more organic based fluids, such as oils, greases, organic solvents, motor oil, hydraulic fluid, brake fluid, automatic transmission fluid, standardized hydrocarbon solutions, such as any of the solutions from the 3M Test Kit, or any mixture thereof. The samples of the protection barriers 100, 200 can be monitored and recorded for any time period, such as, for example, from about 15 minutes to about 24 hours or about 7 days. As used herein, unless otherwise noted, the OGR spill-catch values are provided in reference to 10 mL of automatic transmission fluid at a temperature of about 23° C.

In some examples, the protection barriers 100 and/or 200 can have an OGR spill-catch value of about 0.1 hr, about 0.5 hr, or about 1 hr to about 1.5 hr, about 2 hr, about 3 hr, about 4 hr, about 5 hr, about 6 hr, about 7 hr, about 8 hr, about 9 hr, about 10 hr, about 11 hr, about 12 hr, about 13 hr, about 14 hr, about 15 hr, about 16 hr, about 17 hr, about 18 hr, about 19 hr, about 20 hr, about 21 hr, about 22 hr, about 23 hr, about 24 hr, about 25 hr, about 26 hr, about 27 hr, about 28 hr, about 29 hr, about 30 hr, about 50 hr, about 100 hr, or longer. In some specific examples, the protection barriers 100 and/or 200 can have an OGR spill-catch value of about 0.5 hr to about 24 hr. In other specific examples, the protection barriers 100 and/or 200 can have an OGR spill-catch value of about 1 hr to about 18 hr. In other specific examples, the protection barriers 100 and/or 200 can have an OGR spill-catch value of greater than 24 hr or greater than 48 hr.

The energy absorbing layers 125 and/or 225 can be similar to the layers 117, 217, and/or 230. For example, the energy absorbing layers 125 and/or 225 can include or contain a plurality of lignocellulosic fibers, natural fibers, synthetic fibers, recycled fibers, or any mixture thereof. The energy absorbing layers 125 and/or 225 can include open cell foam, closed cell foam, or a combination or mixture of open cell foam and closed cell foam. In some specific examples, the energy absorbing layers 125 and/or 225 can contain virgin natural fibers, such as hardwood fibers, softwood fibers, or a mixture thereof.

The energy absorbing layers 125 and/or 225 can be affixed, adhered, attached, fastened, or otherwise secured to the corresponding base sheet 115 and/or 215. For example, one or more adhesives or binders can be used to secure the energy absorbing layer 125 and/or 225 to the corresponding base sheet 115 and/or 215.

In at least one example, the adhesive, if present, can be or include a starch-based adhesive.

For an energy absorbing layer 125 and/or 225 that includes foam, such as open and/or closed cell foam, the foam can have any desired shape or configuration. For example, the foam can be in the form of a continuous sheet or layer. In another example, the foam can be randomly or systematically disposed about the side of the corresponding base sheet 115, 215 in a non-continuous manner such that a plurality of islands or regions of the energy absorbing layer 125 and/or 225 are secured to the corresponding base sheet 115, 215. In another example, the foam can be disposed about the side of the corresponding base sheet 115, 215 in regular patterns such as a plurality of lines such that the foam forms a plurality of ridges along a length or width of the side of the corresponding base sheet 115, 215.

The energy absorbing layers 125 and/or 225 can have a thickness of about 0.005 mm, about 0.01 mm, about 0.02 mm, about 0.03 mm, about 0.04 mm, about 0.05 mm, about 0.1 mm, or about 0.15 mm to about 0.25 mm, about 0.5 mm, about 0.75 mm, about 1 mm, about 1.25 mm, about 1.5 mm, about 1.75 mm, about 2 mm, or greater.

FIGS. 1 and 2 depict the energy absorbing layers 125 and 225 as corrugated or fluted layers without including face boards. However, in other examples, the energy absorbing layers 125 and 225 can be or include single face boards, single wall boards, or multi-wall boards, such as, for example, double wall boards or triple wall boards (not shown). Therefore, each of the energy absorbing layer 125 or 225 can independently include one or more corrugated or fluted layers and one or more wall boards or face boards.

The energy absorbing layers 125 and/or 225 can be a configured to provide a contact surface between the energy absorbing layers 125 and/or 225 and a surface to be protected by the protection barriers 100 and/or 200 having a reduced contact relative to a surface area of a side of the protection barriers 100 and/or 200 that opposes the energy absorbing layers 125 and/or 225. For example, the contact area between the energy absorbing layers 125 and/or 225 can be about 5% less, about 10% less, about 15% less, about 20% less, about 25% less, about 30% less, about 35% less, about 40% less, about 45% less about 50% less about 55% less, about 60% less, about 65% less, about 70% less, about 75% less, about 80% less, about 85% less, about 90% less, or about 95% less than a surface area of the protection barrier 100 and/or 200 that opposes the energy absorbing layer 125 and/or 225. For example, an energy absorbing layer 125 and/or 225 that includes a corrugated layer having a plurality of flutes or a plurality of ridges formed by securing open and/or closed cell foam along a side of the protection barrier 100 and/or 200 can have a reduced contact area of about 25% to about 85%, about 50% to about 75%, about 65% to about 80%, or about 35% to about 75% less than a surface area of the of the protection barrier 100 and/or 200 that opposes the energy absorbing layer 125 and/or 225. Reducing the contact area between the energy absorbing layer 125 and/or 225 and a surface to be protected can reduce the tendency or likelihood that the protection barrier 100 and/or 200 may cause scratches or other surface disruptions in a surface to be protected when located thereon.

The sizing layers 320-323 can have the OGR property for providing a barrier to one or more oils, greases, fats, or other organic-based compounds or materials. Illustrative organic-based compounds or materials can include, but are not limited to, oils, greases, fats, organic solvents, motor oil, hydraulic fluid, brake fluid, automatic transmission fluid, or any mixture thereof. In some examples, one or more of the layers 330-334 can have the OGR properties as sizing layers 320-323, and/or the energy absorbing layer 340.

In one aspect, the OGR property can be measured or otherwise determined by using a test kit referred to as the “3M Test Kit” (TAPPI T-559 standard test for Grease Resistance for Paper and Paperboard, established by the Technical Association of the Pulp and Paper Industry, Norcross, Ga., USA; and commercially available from 3M Company, St. Paul, Minn., USA). The “3M Test Kit” includes 12 solutions composed of castor oil, toluene, and n-heptane having various concentrations. Each oil solution can be applied to a sample portion of the sizing layers 320-323. The highest numbered solution (the most aggressive) that remains on the surface of the sizing layers 320-323 without causing failure (e.g., soaking through the layer) is scored as integers from 0 to 12 (worst to best) based on the liquid wetting and penetrating and is reported as the OGR value. The test can be repeated multiple times and the average OGR value can be calculated for each sample.

The sizing layers 320-323 can independently have an average OGR value of about 6, about 6.2, about 6.4, about 6.6, about 6.8, about 7, about 7.2, about 7.4, about 7.6, about 7.8, about 8, about 8.2, about 8.4, about 8.6, about 8.8, about 9, about 9.2, about 9.4, about 9.6, about 9.8, about 10, about 10.1, about 10.2, about 10.3, about 10.4, about 10.5, about 10.6, about 10.7, about 10.8, about 10.9, about 11, about 11.1, about 11.2, about 11.3, about 11.4, about 11.5, about 11.6, about 11.7, about 11.8, about 11.9, about 12, as measured according to TAPPI T-559 standard test for Grease Resistance for Paper and Paperboard. In some examples, the sizing layers 320-323 can independently have an OGR value or an average OGR value of about 6 to about 12, about 8 to about 12, about 10 to about 12, about 8 to about 11, or about 6 to about 10, as measured according to TAPPI T-559 standard test for Grease Resistance for Paper and Paperboard.

The OGR property of the protection barrier 300 can be measured or otherwise determined by using a boat float test, according to the Georgia-Pacific Flotation Paper Saturation Test STP-415. In the boat float test, the protection barrier 300 is folded into a boat-shaped sample, then floated in a wetting solution for a given time period. An OGR flotation value can be determine by the amount of time that the boat-shaped sample has successfully remained floating in the wetting solution (as opposed to sinking in the wetting solution). The wetting solution can be or include one or more organic based compounds, oils, greases, organic solvents, standardized hydrocarbon solution, such as motor oil, hydraulic fluid, brake fluid, automatic transmission fluid, any of the solutions from the 3M Test Kit (e.g., solutions can include castor oil, toluene, or n-heptane), or any mixture thereof. As used herein, unless otherwise noted, the OGR flotation values can be measured according to the Georgia-Pacific Flotation Paper Saturation Test STP-415 with automotive brake fluid at a temperature of about 100° C.

In some examples, the protection barrier 300 can be folded into a boat-shaped sample, such as by folding about 2.54 cm of each side of a square sample having side lengths of about 15.24 cm for the protection barrier 300. The protection barrier 300 can be folded so that the upper surface 302 is facing inwards and upwards so to be within the boat-shaped sample while the lower surface 304 is facing downwards and outwards so to be outside of the boat-shaped sample. Each of the corners of the boat-shaped sample can be stapled. The wetting solution (e.g., hydraulic fluid or automotive brake fluid) contained within a vat can be heated and maintained at about 100° C. The boat-shaped sample of the protection barrier 300 can be placed into heated wetting solution such that the upper surface 302 is disposed facing away from the wetting solution and the lower surface 304 is disposed facing into the heated wetting solution. The time that the boat-shaped sample of the protection barrier 300 can be monitored and recorded for any time period, such as, for example, about 30 seconds or about 3 months.

In some examples, the protection barrier 300 can have an OGR flotation value of about 0.1 hr, about 0.5 hr, about 1 hr, about 2 hr, about 3 hr, about 4 hr, about 5 hr, about 6 hr, about 7 hr, about 8 hr, about 9 hr, about 10 hr, about 11 hr, about 12 hr, about 13 hr, about 14 hr, about 15 hr, about 16 hr, about 17 hr, about 18 hr, about 19 hr, about 20 hr, about 21 hr, about 22 hr, about 23 hr, about 24 hr, about 25 hr, about 26 hr, about 27 hr, about 28 hr, about 29 hr, about 30 hr, about 50 hr, about 100 hr, or longer, as measured according to the Georgia-Pacific Flotation Paper Saturation Test STP-415. In some specific examples, the protection barrier 300 can have an OGR flotation value of about 4 hr to about 24 hr. In other specific examples, the protection barrier 300 can have an OGR flotation value of about 8 hr to about 24 hr. In other specific examples, the protection barrier 300 can have an OGR flotation value of greater than 24 hr or greater than 48 hr.

The OGR property of the protection barrier 300 can also be measured or otherwise determined by using a spill catch test. In the spill catch test, a sample of the protection barrier 300 is disposed onto a flooring surface, then a wetting fluid is added to the upper surface 302. After a given time period, the flooring surface is checked for the presence of the wetting fluid. An OGR spill-catch value can be determine by the maximum amount of time that lapsed from exposing the wetting fluid to the sample to the time the flooring surface is checked and remains free of the wetting fluid. The protection barrier sample can be a square sample having side lengths of about 15.24 cm for the protection barrier 300. The wetting fluid can be or include one or more organic based fluids in an amount of about 10 mL, such as oils, greases, organic solvents, motor oil, hydraulic fluid, brake fluid, automatic transmission fluid, standardized hydrocarbon solutions, such as any of the solutions from the 3M Test Kit, or any mixture thereof. The samples of the protection barrier 300 can be monitored and recorded for any time period, such as, for example, from about 15 minutes to about 24 hours or about 7 days. As used herein, unless otherwise noted, the OGR spill-catch values are provided in reference to 10 mL of automatic transmission fluid at a temperature of about 23° C.

In some examples, the protection barrier 300 can have an OGR spill-catch value of about 0.1 hr, about 0.5 hr, or about 1 hr to about 1.5 hr, about 2 hr, about 3 hr, about 4 hr, about 5 hr, about 6 hr, about 7 hr, about 8 hr, about 9 hr, about 10 hr, about 11 hr, about 12 hr, about 13 hr, about 14 hr, about 15 hr, about 16 hr, about 17 hr, about 18 hr, about 19 hr, about 20 hr, about 21 hr, about 22 hr, about 23 hr, about 24 hr, about 25 hr, about 26 hr, about 27 hr, about 28 hr, about 29 hr, about 30 hr, about 50 hr, about 100 hr, or longer. In some specific examples, the protection barrier 300 can have an OGR spill-catch value of about 0.5 hr to about 24 hr. In other specific examples, the protection barrier 300 can have an OGR spill-catch value of about 1 hr to about 18 hr. In other specific examples, the protection barrier 300 can have an OGR spill-catch value of greater than 24 hr or greater than 48 hr.

The sizing layers 420 and/or 520 can have the OGR property for providing a barrier to one or more oils, greases, fats, or other organic-based compounds or materials. Illustrative organic-based compounds or materials can include, but are not limited to, oils, greases, fats, organic solvents, motor oil, hydraulic fluid, brake fluid, automatic transmission fluid, or any mixture thereof.

In one aspect, the OGR property can be measured or otherwise determined by using a test kit referred to as the “3M Test Kit” (TAPPI T-559 standard test for Grease Resistance for Paper and Paperboard, established by the Technical Association of the Pulp and Paper Industry, Norcross, Ga., USA; and commercially available from 3M Company, St. Paul, Minn., USA). The “3M Test Kit” includes 12 solutions composed of castor oil, toluene, and n-heptane having various concentrations. Each oil solution can be applied to a sample portion of the sizing layers 420 and/or 520. The highest numbered solution (the most aggressive) that remains on the surface of the sizing layers 420 and/or 520 without causing failure (e.g., soaking through the layer) is scored as integers from 0 to 12 (worst to best) based on the liquid wetting and penetrating and is reported as the OGR value. The test can be repeated multiple times and the average OGR value can be calculated for each sample.

The sizing layers 420 and/or 520 can independently have an average OGR value of about 6, about 6.2, about 6.4, about 6.6, about 6.8, about 7, about 7.2, about 7.4, about 7.6, about 7.8, about 8, about 8.2, about 8.4, about 8.6, about 8.8, about 9, about 9.2, about 9.4, about 9.6, about 9.8, about 10, about 10.1, about 10.2, about 10.3, about 10.4, about 10.5, about 10.6, about 10.7, about 10.8, about 10.9, about 11, about 11.1, about 11.2, about 11.3, about 11.4, about 11.5, about 11.6, about 11.7, about 11.8, about 11.9, about 12, as measured according to TAPPI T-559 standard test for Grease Resistance for Paper and Paperboard.

The OGR property of the protection barriers 400 and 500 can be measured or otherwise determined by using a boat float test, according to the Georgia-Pacific Flotation Paper Saturation Test STP-415. In the boat float test, the protection barriers 400 and 500 are folded into a boat-shaped sample, then floated in a wetting solution for a given time period. An OGR flotation value can be determine by the amount of time that the boat-shaped samples have successfully remained floating in the wetting solution (as opposed to sinking in the wetting solution). The wetting solution can be or include one or more organic based compounds, oils, greases, organic solvents, standardized hydrocarbon solution, such as motor oil, hydraulic fluid, brake fluid, automatic transmission fluid, any of the solutions from the 3M Test Kit (e.g., solutions can include castor oil, toluene, or n-heptane), or any mixture thereof. As used herein, unless otherwise noted, the OGR flotation values can be measured according to the Georgia-Pacific Flotation Paper Saturation Test STP-415 with automotive brake fluid at a temperature of about 100° C.

In some examples, the protection barriers 400, 500 can be folded into a boat-shaped sample, such as by folding about 2.54 cm of each side of a square sample having side lengths of about 15.24 cm for each protection barrier 400, 500. Each protection barrier 400, 500 can be folded so that the upper surfaces 402, 502 are facing inwards and upwards so to be within the boat-shaped sample while the lower surfaces 404, 504 are facing downwards and outwards so to be outside of the boat-shaped sample. Each of the corners of the boat-shaped sample can be stapled. The wetting solution (e.g., hydraulic fluid or automotive brake fluid) contained within a vat can be heated and maintained at about 100° C. The boat-shaped samples of the protection barriers 400, 500 can be placed into heated wetting solution such that the upper surfaces 402, 502 are disposed facing away from the wetting solution and the lower surfaces 404, 504 are disposed facing into the heated wetting solution. The time that the boat-shaped samples of the protection barriers 400, 500 can be monitored and recorded for any time period, such as, for example, about 30 seconds or about 3 months.

In some examples, the protection barriers 400 and/or 500 can have an OGR flotation value of about 0.1 hr, about 0.5 hr, about 1 hr, about 2 hr, about 3 hr, about 4 hr, about 5 hr, about 6 hr, about 7 hr, about 8 hr, about 9 hr, about 10 hr, about 11 hr, about 12 hr, about 13 hr, about 14 hr, about 15 hr, about 16 hr, about 17 hr, about 18 hr, about 19 hr, about 20 hr, about 21 hr, about 22 hr, about 23 hr, about 24 hr, about 25 hr, about 26 hr, about 27 hr, about 28 hr, about 29 hr, about 30 hr, about 50 hr, about 100 hr, or longer, as measured according to the Georgia-Pacific Flotation Paper Saturation Test STP-415. In some specific examples, the protection barriers 400 and/or 500 can have an OGR flotation value of about 4 hr to about 24 hr. In other specific examples, the protection barriers 400 and/or 500 can have an OGR flotation value of about 8 hr to about 24 hr. In other specific examples, the protection barriers 400 and/or 500 can have an OGR flotation value of greater than 24 hr or greater than 48 hr.

The OGR property of the protection barriers 400 and 500 can also be measured or otherwise determined by using a spill catch test. In the spill catch test, a sample of the protection barrier 400 or 500 is disposed onto a flooring surface, then a wetting fluid is added to the upper surface 502 or 502. After a given time period, the flooring surface is checked for the presence of the wetting fluid. An OGR spill-catch value can be determine by the maximum amount of time that lapsed from exposing the wetting fluid to the sample to the time the flooring surface is checked and remains free of the wetting fluid.

Furthermore, the colorant can provide a surface that evenly absorbs heat. The colorant can be used to better distribute heat about the surface of the protection barriers 100-800 so that hot spots do not develop in the surface of the protection barriers 100-800 when a light source, e.g., sunlight or light from a lamp, is directed toward the protection barriers 100-800.

In some examples, one or more protection barriers (e.g., any of the protection barriers 100-800) can be made and include a base sheet that can contain at least one paperboard layer and at least one sizing layer. One of the paperboard layers can form a first outer surface of the base sheet and one of the sizing layers can form a second outer surface of the base sheet. An energy absorbing layer can be attached or otherwise coupled to the paperboard layer which forms the first outer surface of the base sheet. A facing layer can be attached or otherwise coupled to the energy absorbing layer. The energy absorbing layer and the facing layer can be attached or otherwise coupled together, and then the combined layers via the energy absorbing layer can be attached or otherwise coupled to the first outer surface of the base sheet. In some examples, a scratch protective layer can be attached or otherwise coupled to the facing layer. In other examples, the scratch protective layer can be attached or otherwise coupled to the sizing layer forming the second outer surface of the base sheet.

One or more protection barriers (e.g., any of the protection barriers 100-800) can be installed by applying the protection barrier to one or more surfaces (e.g., a floor or a deck) in a building, house, or other structure. The surfaces, desired to be protected or otherwise at least partially covered by the protection barriers, can contain or include one or more materials, such as stone, rock, granite, quartz, terrazzo, marble, ceramic, concrete, colored concrete, brick, mortar, tile, masonry material, wood, plastic, linoleum, epoxy, glass, metal (e.g., copper, brass, stainless steel, aluminum, or alloys thereof), composite flooring, composite countertops, or any mixture thereof. The surfaces can be or part of one or more interior surfaces, exterior surfaces, or any other surface desired to be protected by one or more protection barrier (e.g., any of the protection barriers 100-800). The surfaces can be or part of one or more floors, decks, walls, countertops, cabinets, stairs, elevator interior surfaces, painted surfaces, concrete or cement surfaces, or any other surface desired to be protected by a protection barrier (e.g., any of the protection barriers 100-800).
